Abstract
A rotary oxygenization ejector comprises a pressure water pipe, an air tube and an ejector, and is characterized in that a nozzle communicated with the pressure water pipe is provided in the ejector; the nozzle is of conical shape, and is of a same concentric line with a throat which is movably fit to between the nozzle and the ejector. An air chamber is formed between the nozzle and the throat; the throat is a straight tube. Air tubes are provided on one side or both sides of the top of the ejector. The lower end of the throat is permanently with rotary feed pipes; each of the feed pipes extends downwards, and bends to form a level segment. A level or downwards inclined gas-liquid spout is provided at the end of the feed pipe. The gas-liquid spout is equispaced on circumference around the axial line of the ejector in the direction, which is tangential to the circumference and contrary to the rotation direction of the rotary feed pipe. The utility model has the advantages of low cost, low dissipation of energy, easiness to be maintained. The utility model jets in a rotary manner through a plurality of gas-liquid spouts, can not only significantly increase service area, but also fully convert the energy provided by pressure water so that air is cut into microscopic bubbles which will enter the basin; accordingly, bubbles are prevented from gathering again, and utility model meets the requirement for microbes to dissolve oxygen.
